Sometimes you will have to edit paths manually to be able to compile and run POY. Bellow are a few tips that may come in handy for first time users.

SET PATHS
	You can set the default path for all users in /etc/login.defs. For example:
		ENV_SUPATH PATH=/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin:/extra/dir
		ENV_PATH PATH=/usr/local/bin:/usr/bin:/bin:/extra/dir
	You can also add a directory to PATH in /etc/bash.bashrc.local. For example:
		PATH=$PATH:/my/myscripts
		export PATH
	
SET LIBRARY PATH
	New paths can be added into /etc/bash.bashrc.local, which will be read upon reboot.
	You can also export the path directly just for the current section.
	Example:
		$ export LD_LIBRARY_PATH=.:/some/path/:/other/path/:$LD_LIBRARY_PATH
	To check the variable LD_LIBRARY_PATH execute:
		$ echo $LD_LIBRARY_PATH
	To unset a LD_LIBRARY_PATH execute:
		$ unset LD_LIBRARY_PATH
	In some cases you may also need to add the library so it will be recognized by the ldconfig command. In order to do that, creat a text file in /etc/bash/bashrc.local.d/ with some name and the .conf extension.  Inside it. paste just the path of the library folder.
	Refresh ldcongid by executing this:
		$ sudo /sbin/ldconfig
	Chack if the new libraries are there:
		$ sudo /sbin/ldconfig -v
	Do this before compiling programs that requires new libraries.
	TIP: you can see if the executable nows where eveything he need is by executing ldd:
		$ ldd <executable>
	But even if he finds everything, some times it will not work if tha library was in a declared path that was not recognised by ldconfig before compilation.
